i agree with the suggestion of a king single bed for dd. it was a winner here. it meant dh could help settle her while being comfortable. I found it too difficult to get up again (i was pg too), so put a comfy chair next to DDs bed.

even if you don't get things under control by when baby arrives, you will get through. i sometimes bf baby while sitting next to dd in her bed reading a story. or bf baby and then rocked him in a rocker with a hand or foot while feeding/working with dd. my dh does shift work, so i don't always have a second pair of hands and we have all survived so far!
